Privilege elevation in the Windows App Store component affects a broad range of Microsoft Windows client and server releases (Windows 10 1607 through Windows 11 26H1, and Windows Server 2016 through 2025), where a race condition (CWE-362) lets an unauthorized attacker win a timing window to gain elevated privileges over a network. The CVSS 3.1 score is 8.1 with a network vector and no authentication (PR:N), but high attack complexity (AC:H) reflects the difficulty of reliably winning the race. There is no public exploit identified at time of analysis and it is not listed in CISA KEV; a vendor patch is available from Microsoft.

Cleartext transmission of sensitive information in Windows Ancillary Function Driver for WinSock allows an authorized attacker to disclose information locally.

Exposure of sensitive information to an unauthorized actor in Windows Media allows an authorized attacker to disclose information locally.

Local privilege escalation in Windows Secure Kernel Mode (SKM/VTL1) allows an already-authenticated attacker to elevate to higher privileges on affected Windows 10, Windows 11 (through 26H1), and Windows Server 2016-2025 systems. The flaw stems from improper consistency validation of input crossing the trust boundary into the isolated secure kernel (CWE-1288), yielding full confidentiality, integrity, and availability impact on the local host. Microsoft has released a patch; there is no public exploit identified at time of analysis and the CVE is not listed in CISA KEV.

Remote code execution in the Microsoft 365 Copilot mobile apps for Android and iOS lets an unauthenticated attacker run code across a security boundary by getting a user to interact with crafted content (CWE-77 command injection). The CVSS 9.6 rating reflects network reach, low complexity, no privileges, and a changed scope with high confidentiality, integrity, and availability impact. There is no public exploit identified at time of analysis, but a vendor patch is available and the flaw was self-reported by Microsoft.

Local privilege escalation in the Citrix Secure Access Client and Citrix Endpoint Analysis (EPA) Client for Windows allows a low-privileged local user to gain higher (likely SYSTEM-level) privileges through improper privilege management (CWE-269). It affects Secure Access Client for Windows before 26.6.1.20 and Endpoint Analysis Client for Windows before 26.5.1.7, both of which run privileged Windows service/agent components on the endpoint. There is no public exploit identified at time of analysis and it is not listed in CISA KEV, but Citrix rates the flaw high severity (CVSS 4.0 base 8.5) given full confidentiality, integrity, and availability impact once exploited.

Out-of-bounds read in Citrix Secure Access Client for Windows (all versions before 26.6.1.20) enables a local low-privileged attacker to read memory beyond an allocated buffer boundary, resulting in high confidentiality impact with no integrity or availability consequence. The CVSS 4.0 score of 6.8 reflects the local attack vector and low-privilege requirement, meaning an attacker must already hold a foothold on the endpoint. No public exploit code and no active exploitation (CISA KEV) have been identified at time of analysis.

Local privilege escalation in Bitdefender Total Security and Internet Security for Windows (versions before 27.0.58.315) lets a less-privileged local user gain higher rights by abusing a symbolic-link race condition in the File Shredder module. Because the shredder operates with elevated privileges and does not safely resolve links before acting on files, an attacker who wins a time-of-check/time-of-use race can redirect a privileged file operation to a target of their choosing. No public exploit identified at time of analysis; the issue was reported by the vendor and requires local access plus user interaction, so EPSS-style mass-exploitation risk is limited.

Arbitrary code execution in SAProuter on Microsoft Windows lets a local attacker plant a malicious DLL in an untrusted search-path location that SAProuter loads at runtime, hijacking the DLL loading process to run attacker code with the privileges of the SAProuter service. The flaw was reported by SAP and carries a CVSS 8.4 with full High impact on confidentiality, integrity, and availability; there is no public exploit identified at time of analysis and it is not listed in CISA KEV. Because SAProuter typically runs as a persistent network gateway service, successful exploitation can compromise a strategically positioned host in an SAP landscape.

A Denial of Service (DoS) vulnerability exists in the receive loop of libmodbus 3.1.12 when running on Windows. The issue stems from improper timeout management during network read operations.

Privilege elevation in Microsoft Edge (Chromium-based) lets a network attacker escalate privileges by luring a victim into loading crafted web content that triggers an untrusted pointer dereference (CWE-822). Microsoft rates it CVSS 8.3, driven by a scope change (sandbox/boundary crossing) and full confidentiality, integrity, and availability impact, but exploitation requires user interaction and is of high attack complexity. No public exploit identified at time of analysis (E:U), it is not on CISA KEV, and an official vendor fix is available.

Remote code execution in Microsoft Edge (Chromium-based) lets an unauthenticated network attacker run arbitrary code by luring a victim into interacting with crafted content that triggers unsafe deserialization (CWE-502). The flaw carries CVSS 8.3 with a scope change, meaning successful exploitation can break out of the browser's security boundary, though there is no public exploit identified at time of analysis and Microsoft has already shipped a fix.

Stored XSS execution in Parse Server (versions 9.0.0 through pre-9.10.0-alpha.2 and all 8.x releases through 8.6.83) allows authenticated users with file-upload permissions to inject persistent JavaScript that executes in the application's origin against other users, but only when a cloud-based storage adapter is configured. By crafting a deliberately malformed Content-Type header - such as 'image' or 'image/' - an attacker exploits a gap in the mime-package lookup path that renders the fileUpload.fileExtensions blocklist ineffective, causing the malformed value to be stored verbatim in Amazon S3, Google Cloud Storage, or Azure Blob Storage. Browsers receiving a syntactically invalid Content-Type fall back to MIME sniffing and render HTML file bodies as web pages in the application's origin; no public exploit has been identified and the vulnerability is absent from CISA KEV, but the stored nature means a single successful upload persists as a live threat until patched or the file is removed.

Unauthenticated remote code execution in the PrestaShop ps_facetedsearch (layered navigation) module versions 3.0.0 through 4.0.3 allows a single crafted front-office request to fully compromise the shop and its underlying server. The module rebuilds price/weight slider filter values from the request URL and later reads them back through a native unserialize(), enabling PHP object injection whose gadget chain writes a PHP webshell into the module directory. No public exploit is identified at time of analysis, but the flaw is trivially reachable and rated CVSS 10.0.

Authenticated RabbitMQ users can bypass authorization controls on passive AMQP 0-9-1 declare operations, exposing internal broker topology metadata across all affected release branches (3.13.x, 4.0.x, 4.1.x, 4.2.x). The missing authorization check on passive queue.declare and exchange.declare allows any user with vhost connectivity to enumerate queue and exchange names and read live message and consumer counts without requiring elevated permissions. No public exploit code has been identified and the vulnerability is not in CISA KEV; however, the low exploitation complexity, authentication-only prerequisite, and broad affected version range meaningfully elevate real-world exposure risk in multi-tenant or shared-credential deployments.

Stored cross-site scripting in the RabbitMQ management UI (versions prior to 4.2.5) lets a user holding queue/exchange declaration permissions inject JavaScript that executes in another user's browser when they view the Queues or Exchanges pages. The malicious payload is supplied via the x-internal-purpose queue or exchange argument, which is rendered into an HTML title attribute without escaping. There is no public exploit identified at time of analysis, and the issue is not listed in CISA KEV; it is fixed in RabbitMQ 4.2.5.

Server-side request forgery and NTLM credential exposure in the RabbitMQ management plugin (versions 4.1.0 to before 4.1.11 and 4.2.0 to before 4.2.6) on Windows lets remote actors coerce the broker into outbound DNS and SMB connections to attacker-controlled UNC paths. The static file handler rabbit_mgmt_wm_static passes URL-encoded backslashes to erl_prim_loader:read_file_info before path validation, but only when multiple management extension plugins are enabled. No public exploit has been identified at time of analysis, and the EPSS score is low (0.28%, 20th percentile) despite the CVSS 10.0 rating.
